To (tZZ whont it ntcty concern:

Be it known that I, OLIVER ELISON, a citizen of the United States,residing at Concord, in the county of Dixon and State of Nebraska, haveinvented a new and useful Mowing-Mac'hine,of which the following isaspecification.

The objects of my invention are to provide in a mowing'machine amechanism for shifting the cutter-bars, by which means they areprotected from injury when they encounter any obstructions, to increasethe cutting power of the machine, and to greatly reduce the speed ormotion of its mechanism; to provide a mechanism operated with the feetby means of which the drag-bar and cutterbars are controlled, raised toa perfect up right position, also lowered; to provide a mechanism forraising and lowering the dragbar and cutter-bars independently of themain frame for high and close cutting without tilting the main frame,drag bar, or cutter-bars, and, further, to provide a mechanism whichdispenses with the clutch mech anism in the hubs of the drivewheels,which admits the use of drive Wheels of light Weight. These advantagesalso admit of greatly reducing the weight, draft, and wear of themachine. All of these advantages are obtained by the combination of theseveral parts, as described hereinafter.

In the accompanying drawings, Figure l is a top view of a mowing-machineembodying my invention. Fig. 2 is a front elevation of the same. Fig. 3is a side elevation of the same. Fig. it is a top view of the machinewith portions removed. Fig. 5 is a top view of the cutting apparatuswith portions removed. Fig. 6 -is an enlarged view of the outer end ofthe cutting apparatus. Fig. 7 is a sectional view taken on the line 00 wof Fig. 6. Fig. 8 is an enlarged view of the inner end of the cuttingapparatus. Fig. 9 is a sectional view on the line yy of Fig. 8.

'Fig. 10 is an enlarged top view of the outer end of the guidebar. Fig.11 is a perspective view of the upper portion of the box secured to theguide-bar. Fig. 12 is a similar view of the lower portion of the same.Fig. 13 is a perspective view of the yoke. Fig. 14 is an enlarged viewof the outer ends of the cutter-bars and guide-bar. Fig. 15 is anenlarged View of the foot-loops secured to the rock-shaft. the keepers.

The main frame A, the upper transverse bar N, the lower transverse bar Dthe upper central longitudinal bar D, the lower longitudinal bars D Dand the parallel bars 61 d constitute the framework of the machine. Themain axle B, which is divided in two parts, is revolubly held to themain frame A by means of bearings 3 3, secured to the sides of the mainframe, and the bean ings 3 3, secured to the parallel bars d anddrivewheels U C, are rigidly secured to this axle. A tongue T is securedto the main frame by means of a bearing 82, secured to the transversebar N, and a bearing 19, secured to the front portion of the main frame.These bearings extend downward below the main frame and are perforatedto receive a supporting-shaft 42 and a rock-shaft 70. A bar 83, fixedbetween the bars D and D supports the rear end of the rock-shaft.

The shaft 42 extends forward of-the main frame A, and a couplingframeconsisting of the arms I I, a bar at, and a yoke 84 is pivoted to thisshaft, the bar 07. extending from the forward end of this shaft to thedownward-extending front portion 84 of the yoke 84. The transverse bar Dand the two longitudinal bars D D curve downward to sup port the drivingmechanism, the forward ends of the bars D being secured to the bars DThe small sprocket-wheel G and the large bevel-gear F, rigidly securedto the transverse shaft 40, held by the bearings 40", secured to thebars D, the small bevel-pinion G and the crank H, rigidly secured to thecrank-shaft 41, held by the bearings 41, secured to a forward-extendingsupport 42, secured to the bar D the large sprocket-wheel E, held uponthe main axle B, and the endless chain belt e upon these sprocket-wheelsconstitute the driving mechanism Within the main frame.

Fig. 16 is a perspective view of A drag-bar 10, having a divide, or shoeX secured to its outer end and a shoe K'secured to its inner end, ispivoted to the yoke 84 of the coupling-frame by means of pins 78 78,which extend through corresponding 1 holes in the shoe K and this yoke.

The mechanism for shifting the cutter-bars comprise the grooved keeperb,secured to tho outer end of the drag-bar 10, and the keeper 1'), alsogrooved, secured within the shoe K at the inner end of the drag-bar, theguidebar 46 working in the grooves of these keepers, theforwardly-drawing bow-spring 6, secured to a projection X of the shoe X,the lug 46 secured to the under side of the outer end of this guide-bar,the link 7, which connects this lug and the forwardly-drawingbow-spring, the bar 5, provided with a pin 5, the forward end of thisbar pressing against the lower box J, its rear end projecting through anopening in the rear portion of the shoe K, and the forwardly-pressingcoiled spring 4 upon this bar. (Shown in Figs. 6, 7, 8, 9, and 10.)

Secured to theinner end of the guide-bar 46 is a box J. This box is intwo parts, their corresponding edges being bent outward to formflangesfj the upper portion J of the box being secured to the lowerportion J by means of bolts 'i, extending through corresponding holes inthese flanges and secured by nutsj' upon these bolts. Extending from thebox J and reposing upon the guide-bar 46 are two cutter-bars or sicklesL M. These cutter-bars are provided with corresponding longitudinalslots 3, and the guide-bar is pro-' vided with tapering holes 46opposite the slots 3 in the cutter-bars. Guides Y, extending through theslots 3 in the cutter-bars and the holes 46, hold and guide thecutter-bars upon the guide-bar 46, these guides and holes tapering fromtheir edges, the lower ends of the guides terminatingin boltconformations and are threaded to receive nuts y, which secure theseguides to the said guide-bar, as shown in Fig. 7. A rack U is secured tothe inner end of the lower eutterbar, and a rack R is secured to theinner end of the upper cutter-bar.

Extending through the box J is a rock-shaft 45, the two partsconstituting this box conjointly forming the bearings for this rockshaft and holding it. Rigidly secured to this rock-shaft 45 Within thebox J and meshing the racks R and Usecured to the cutter-bars, is aspur-pinion Q, and rocker-arms 2 2 are rigidly secured to the projectingends of the rock-shaft.

The inner end of the upper cutter-bar L is bent upward to pass over thepinion Q and engage it, the blank portion of the rack R extending downthe bend of this cutter-bar to strengthen it. The upper portion J of thebox is provided with inwardly-extending fiangesjt These flanges extendonly a part of the distance of the length of this box, which is toprovide for the removal of the upper portion J, which is accomplished byremoving the boltsj and moving the upper cutter-baroutwardly untilitdisengages these flanges. (Shown in Fig. 5.) These flanges j serve asa guide or support for the inner end of the upper cutter-bar.

The outer end of the lower portion J of the box is open for the purposeof inserting and removing the cutter-bars, the outer end of the upperportion J continuing downward and outward to cover the outer end of thelower portion J of the box. A pitman comprising a head and rod portionP- and a frame P, pivoted to this rod portion, connects the drivingmechanism and the rocker-arms 2 2, the rod portion extending through ahorizontal slot 88 in the frame, the pivotal connection being atp to thecross-bar of the frame, and the slot is of sufficient length to permitthe frame to adjust itself to the shifting positions of the cutter-bars,the rod portion normally bearing against the rear end of the slot, andthe outer end portions of the frame are split or parted to stride therocker-arms, to which they are connected by means of pins 2, extendingthrough corresponding holes in the outer portions of the frame and therocker-arms.

To prevent the pitman from binding upon the pin 1 of the crank H whenthe cutter-bars shift rearwardly, the bore in the head portion of thispitman converges slightly from the ends toward the center. The forwardend of the bar 5 enters an indentation 7' in the lower portion J of thebox, which indentation is located opposite the guide-bar 46 and thecutter-bars. The open coiled spring 4, located on this bar and pressingagainst the inside of the rear wall of the shoe K, and the pin 5,extending through this bar, forces this bar 5, and consequently theinner end of said guidebar and cutter-bars, forward to their normalposition. The forward ends of the grooves 19 in the keepers b areclosed, which serve as forward stops for the guide-bar and cutterbars.The lower end of the fiat spring 6,secured to the outside of the shoe X,is provided with a slot 6. The link 7 extends through'this slot and isheld by a pin 7, which extends through one of a series of perforations 7in this link. The outer end tension of the cutter-bars may be regulatedby adjusting the link 7 upon the forwardly-drawing bow-spring 6, and thetension of the inner end of the cutter-bars may be regulated byinserting the pin 5' through any one of a series of perforations 5 inthe bar 5. The shoe X is provided with outwardly-extending edges X whichprotect the mechanism secured to the outside of this shoe. From this itwill be seen that when the machine is drawn forwardly it will cause thearms 2 to rock, imparting a reciprocating movement to the cutter-bars;that these rocker-arms have leverage power over the cutter-bars,affording great cutting power, and that the cutterbars operate as wellin a perfect upright pothe cutter-bars are held under spring tension,

so that when they encounter any obstruction they will automaticallyshift backwardly to a point where the strain of such obstruction isagainst the said drag-bar and automatically return when released fromsuch obstruction, and that either end of the cutter-bars canautomatically recoil independently of the other end, which movement isessential when an obstruction strikes one end of the cutterbars. Theguide-bar 46, upon which the cutfer-bars work, has its ends slightlyrounded, (shown at b,) so that it cannot bind in the grooves of thekeepers b when one end of the cutterbars recoil, and these keepers arecountersunk into the top end portions of this guide-bar, so that thecutter-bars can work over the said keepers.

The cutter-bars comprise two long bars each provided with aseries ofsectional knives L M. These sectional knives are secured to theirrespective bars in such a manner that they conjointly form a cuttingedge. These sectional knives are countersunk into their respective barsto a depth equal to their thickness, and both ends of the rivets whichsecure these knives are also countersunk. (Shown in Fig. 14.) It shouldalso be observed that these bars L and M are very wide and that sundryof the guides Y are located near the front portion and sundry of themnear the rear portion of these bars, which will cause the knives L and Mto be held close together, insuring perfect cutting.

In order to get the cutter-bars positioned as close to the ground aspossible for close cutting, the material of which the shoe K isconstructed is reduced in thickness and the drag-bar 10 is reduced inthickness and correspondingly increased in width, and to insuresufficient strength this shoe is constructed of a material whichcombines great strength and elasticity. The bottom of this shoeK to awidth equal to the length of the keeper b, secured to this shoe, isflat, both the top side and the under side of the bottom being perfectlyflat, and the tongue or draftpole T should be carried at the height thatwill cause this shoe to slide flatly on the ground. The drag-bar iscountersunk into the shoe K to a depth equal to the thickness of itself,and to further strengthen the shoe the drag-bar is countersunk somedistance from the inner end of the shoe, and the portions 84' of theyoke 84 are also intended to hold and strengthen this shoe. A rod 80,secured to the front portion of the shoe K, guides the grain into thecutter-bars.

The rock-shaft 70, the crank-arm 71, and the loops 73, secured to thesaid rock-shaft, the closed coiled spring 72, extending from thiscrank-arm to the left portion of the main frame, the bar 69, connectingthis crank-arm with the shoe K of the drag-bar, the anglepiece V,pivotally held by loops 22, secured to the main frame, the connection26, which connects the crank-arm with one arm of the anglepiece, and thebar 25, which connects the yoke 84 of the coupling-frame with the otherarm of the angle-piece, constitute the mechanism for controlling thecutting apparatus with the feet. By this arrangement the driver hasconstant and perfect control of the cutting apparatus. He can depress,lift, and quickly bring it to a perfect upright position and lower it byexerting a lifting effect on one loop and a depressing effect on theother loop. The tension of the spring 72 can be regulated by theadjustable connection 72 on the main frame.

The connection 26 consists in the combination of a chain and a closedcoiled spring, the chain extending through the spring, the ends of thespring engaging such links in the chain which will leave the inclosedportion of the chain slightly relaxed. By thus combining this chain andspring the inner end of the cutting apparatus can rise above and fallbelow the horizontal line independently to follow unevenness of theground. The bar 69 engages the shoe K of the cutting apparatus at apoint above and outward from the axial pins 78 and exerts a liftingeffect over the outer end of the cutting apparatus, While theconnections 25 and 26 simultaneously exert a similar effect over theinner end of the cutting apparatus through the medium of the rock-shaft70, which is under the immediate control of the driver. A wheel 23,provided with a notch or recess 23, is secured to the rock-shaft 70, anda pawl 23 is pivotally held to the bar D by means of loops 23 This pawl23 extends outward and downward from its pivotal point and rests uponthe rim of the wheel 23. When the cutting apparatus is brought to avertical position, this pawl drops into the recess 23 in the wheel 23,automatically locking the said rockshaft, and this pawl 23 is providedwith an upward-extending projectiomby which it may be disengaged byhand. The means for raising and lowering the cutting apparatus for highand close cutting consists of the eccentric shaft 44, held by the loops44, secured to the rear portion of the drag-bar 10, the ratchetframe 20,secured to the bar cl, the lever O, pivoted to this frame and providedwith a latch mechanism 21, which engages the ratchet of the said frame,and the chain 43, which connects this lever O with the crank portion 44of the eccentric shaft 44, which crank terminates vertically oppositethe pivotal pins 78. When the cutting apparatus rests on the ground,

the crank 44 is at its highest point and the lower end of the lever O isat its forwardmost point. When the upper end of this lever O is movedforwardly, it will cause the eccentric formations 44' to be pressedagainst the ground and raise the cutting apparatus. When the latchmechanism of this lever 'is released, the cutting apparatus is loweredby its own weight. The lever 0 also operates a shaft 75 by means of acrank-arm a, secured to this shaft, and a bar 77, which connects thiscrank-arm with this lever. This shaft a vertical position.

When the cutting apparatus is in a vertical position and the rock-shaftis locked, thekeeper 76 should be caused to engage the drag-bar,(otherwise the strain on the rockshaft and its arm would be too great,)and it is for this reason that the rock-shaft can only be locked Whenthe cutting apparatus is in a position to be engaged by this keeper 76.

The main axle is divided into two parts B and B, and the drive-wheels care rigidly secured to this axle. The collars 24, secured to this axleand working against the inner sides of the bearings 3, prevent the twoparts B B from working apart. The chain-Wheel E is loosely held on thisaxle at a point over the division of the axle. The hub of thischain-Wheel has. clutch terminations which are engaged by correspondingclutch-sleeves 27 27, which are located one near the inner end of eachsection B and B and are provided with longitudinal slots 27, which rideupon pins 27, extending through the axle. These clutch-sleeves arepressed into engagement With the sprocket E by means of springs 27,located upon the axle and backed by the bearings 3, secured to the bars01 d.

The clutch-sleeves 27 are made to disengage and reengage the sprocket Eby means of clutch-levers 81 81, pivoted in an oblique position to theflanges 8 8, secured to the insides of the bars d and d and fitting intoannular grooves 27 27 upon these clutchsleeves, and which clutch-leversare of such conformation that they can be operated conjointly by hand.To disengage the clutch mechanism the free ends of these levers 81 aremoved inwardly until the pawls Z l, pivoted to these levers, drop intothe recesses 9 9 in the bar 9, fixed between the bars 01 and d. (Shownin Figs. 1 and 4:.) A wheel 28, revolubly held upon a shaft 28, securedto hangers 28*, which are adjustably secured to the bars at and d,guides the chain belt 6 and prevents the sprocket-wheel E from Workingsidewise upon the axle, this wheel 28 being located in close proximitywith the large sprocket-wheel. A seat 3, mounted on a seatpost D, issecured to the rear portion of the main frame.

It should benoted that the eccentric form ation at at the outer end ofthe cutting apparatus is located under the keeper 1), which is shaped toconform, which prevents grass or other material from gathering upon it,and that when the cutting apparatus is raised to a vertical position itsweight is thrown upon the chain 26, the inclosing spring lengthening tothat extent.
